About Me
Hi, I’m Bernabe. I’ve been working in IT for over three years, with two of those focused on full-stack development. I’m driven by continuous learning—always experimenting with new technologies and finding ways to automate and build efficient solutions. I have experience managing both Linux and Windows servers, though Linux is where I thrive. I’m most skilled in Linux, JavaScript & networking.
